fo .all whom it may] concern.

Be it known that I, LEE YOUNG DAVIS, citizen of thev United States, residing at Atlanta, in the county of Fulton and State ofv Georgia, have invented certain new and useful Improvements fin Vending Machines; and I ydo hereby declare the following to be a full, clear, and exact'description of" the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in vending machines and more particularly to a device for vending` liquids, grains, and articles of a like character, the main object of the invention being the provision of a vending machine wherein certain quantities of liquid, grain or the like can be dispensed by the deposit of the required amount of coins or tokens within the coin `receiving mechanism.

Another object ofthe present' invention is the provision of a vending machine, whereby the desired quantity of liquid, grain or the like can be readily dispensed by depositing the requisite amount of coins or tokens in the proper coin actuating means, so that shoulda` purchaserY desire aA quart of molasses, vinegar, or the like, he will deposit a coin in the coin receiver adjacent the indicator, which will indicate that a quart o-f liquid can be obtained by4 depositing a coin within this slot.

A further object of the present invention is the provision of a vending apparatus of the above character wherein the liquid lor grain provided in the containers cannot be withdrawn without first depositing therequired amount of coins orl tokens to operate the mechanism which will release the liquids or grain within the propery receptacles. i

With the. above and other objects in view, the invention consists'in the novel features and construction, the combination and arrangement of parts, hereinafter more fully set forth, pointed out in the claims and shown inthe accompanying drawings, in whichy Figure 1 is an elevation of a dispensing device constructed in accordance with my invention, showing one of the receptacles in cross-section and in the operation of being filled, Y

Figure 1() is a diagrammatic view, illustrating severalsmaller containers or measures connected with the main receptacle, whereby vario-us quantities of material can be dispensed, and

F igure 11'isv a diagrammatic view illustrating the smaller measuring vessels in connection Ywith the main container and showing an indicator to indicate the fact that the main container has become. empty.

AInjcarrying out my invention, I provide a series of the receptaclesupon the inside' of the'Wall 1, each receptacle or measuring delvice being provided with individual coin re'- ceiving'and actuating means and a plurality of the measuring receptacles are connected with a main receptacle such as illustrated in Figure 10. Each individual vreceptacle or measuring device includes a tubular body member 2, suitably secured to the inner face of the wall 1 by means of the outturned flanges 3, adapted tobe secured to the wall l in any suitable manner.

These various measuring receptacles are connected to the main receptacle 4- by means of a plurality of conduits 5, .leading from the main receptacle l .to the various measuring receptacles as illustrated in the diagrammatic view in Figure 10. The measuring` re.- ceptacles communicate. directly with the conduits 5 so that the grain or other material will be readily conveyed from the main re.-

lceptacle through the conduits 5 into the measuring receptacles 2. The flow of grain or other material is cut off from the recep# tacles 2 by means of the valve plate 6, which is mounted forvswinging movement upon a pivot 7 said valve plate. being provided with a suitable opening 8, adapted to admit the grain or other material into the receptacles when the valve plate is in its open position. The valve plate 6 is normally retained in a closed position by means of the rod 9 which is connected to the coin expressor 10, the upper end 0f said rod being normally eX- tended through an opening in the plate 6 to retain the plate in .its closed position as illustrated in Figure 4.

The coin operating mechanism used in this form of the invention is arranged adjacent each one of the receptacles 2 and includes in its construction, the coin receiving member 11 provided with the vertically disposed slot 12 in which the coin expressor 10 is movable. The coin expressor is provided with suitable outwardly projecting arms 13 which are adapted to engage with the coin stop 14 to prevent downward movement of the coin expressor when an attempt has been made to move the expressor downwardly withoutfirst depositing the required coin or token within the coin receiver for releasing the grain or other material contained within the receptacle 2.

This control member or stop 14 provides a stop for the coin when the saine is deposited within the chute 15. Thus, after a coin has been de-posited within the chute 15, the same will move downwardly until it rests upon the stop 14, after which the expressor 10 is moved downwardly for engage-ment with the coin, the coin actuating the stop to permit the expressor to pass downwardly beyond the same, as illust-rated in dotted lines in Figure 3. Upon downward movenient of the coin eXpressor, the rod 9 will be moved downwardly so that the same will become disengaged fiom the plate 6 and permit rotation of the plate so thatthe opening 8 can be thrown into alignment with the conduit which supplies the receptacle and thus filling the receptacle for dispensing the i required amountA of material.

After the eXpressor 10 has been moved downwardly to release the plate 6 and the plate 6 has been moved to an open position to permit the receptacle 2 to be filled, the rod 9 which has been previously forced downwardly at its lower end and engaged with the valve plate 16, is moved upwardly to disengage the rod 9 from the valve plate 16 and reengage the same with the plate 6 to retain the plate 6 in its closed position and permit the plate 16 to be opened torelease the material which has been deposited within the receptacle 2. It will be noted that the wall 1 is provided with a slot 17 and the plat-e 6 is formed with a handle 18 adapted to operate within this Vslot 17, wherebyl the plate 6 can be readily actuated by the purchaser from the exteriorv of the wall 1.

The coin expressor 10 is operated through the mediumof a rod 19, which extends .downwardly through a guide sleeve 2O and is provided with an arm 21 which extends transversely and is connected with the coin expressor at a point adjacent the rod 9. The upper end of the rod 19 is provided with a finger plate 22, which can be readily grasped by the operator to force downwardly upon the rod 19 and actuate the coin expressor 10. Each of the valve plates 6 and 16 are provided with suitable coil springs 23 to noi'- mally retain the valve plates 6 and 16 in their closed position, thus after one of the plates has been moved to an open positionV to permit the material to pass therethrough, the handle of the plate is released, the tension of the coil spring returning the plate to its normal closed posit-ion. Y

The pivot pins upon which the plates 6 and 16 are mounted are supported by means of the brackets 24, which are riveted or otherwise secured to the sides of the receptacles 2, so that when the plates are mounted upon these pins, they will be in a position to readily swing between the various sections of the receptacles so asto cut off communication between the same. In Figure 1, it will be noted that the plate 6 is disposed between the upper end of the main receptacle and the conduit'leading therein so that when the plate is in its closed position, as illustrated in Figure 4, the contents of the conduit cannot drop downwardly into the receptacle. It will also be noted that the lower end of the rod 9 is provided with a suitable guide sleeve 25, whereby to guide the same through the opening in the lower plate 16 when it is desired to lock this plate in its closed position, while the receptacle 2 is being iilled.

In the general operation of my improved device for dispensing grain and material of like character, a coin is first deposited within the chute 15, said coin gravitating downwardly under the stop 14 and in order to release the plate 6, so thatthe opening 8 there in can be moved into alignment with the ceptacle 2 andthe conduit 5, the coinV presser 10 is moved downwardly within the slot 12 engaging the coin to force the same beyond the stop 14, this movement will carry the rod 9 downwardly until the upper end thereof is disengaged from the plate 6, permitting the plate 6 to be swung to an open position by means of the handle member 16,V

so that the material from the conduit 5 will readily flow into the receptacle 2.v After the receptacle 2 has been filled, the rod 19 which has been previously forced downwardly to actuate the coin eXpressor 10, will be returned to its normal position by means of the coil spring 26, which is disposed between the linger plate 22 and the shelf portion27, this movement will draw the rod 9 upwardly to release the lower end of the same from the plate 16and again engage the same with the llO til)

plate 6 to retain the plate 6 inl a closed position and permit the plate 16 to be opened. It will be noted that the plate 16 can be readily operated from the outside of the wall 1 by means of a handle member 28 which extends through the front face of the wall to a position whereby it is readily accessible to the operator. Thus, it willbe noted that the plate 16 can be swung to an open position to permit the material from the receptacle 2 to' be drawn olf into any desired container. Communicating withl the lower end of the receptacle 2 is the spout 29 which extends outwardly through the wall 1 so that-the purchaser can readily obtain the material contained within the receptacle 2, which has been released by depositing ythe requisite amount of coins or tokens within the coin receiver.

It will be noted that as each of the plates 6 and 16 is released, the coil springs 23 will return the plates 6 and 16 to their normal closed position, as illustrated upon the left hand side of Figure 1 These coil springs 23 are connected at one end to a pin 30 which is attached to the wall 1, while the other end of the spring is connected to the plate 6 at the inner edge thereof.

In Figures to 9, inclusive, and in Figure 11, I have illustrated the form of the invention particularly adapted for dispensing materials in liquid form, the operation of the coin mechanism and the means for releasing the dispensing valves being substantially the same as that disclosed in the Figures 1 to 4, inclusive. In this form of the invention, the receptacles 2 are provided with offset portions at each end having vertically disposed sleeves 31, in which are mounted the valve members 32 and 33, the valve 33 being arranged at the connection between the receptacle 2 and the inlet pipe 34 which communicates with the main supply pipe 35. The valve member 32 lis provided with `a stem 36 having extended therefrom a plate 37 provided with a perforation to receive the upper end of the rod 9 to retain the valve member 32 in its closed position until a coin has been inserted within the coin chute 15 and the expressor 10 moved downwardly to release the rod 9 from the perforation within the arln 37. This operation will release the valve 32 and permit the same to be rotated by means of a handle member 3S, secured to the stem 36 and proliecting through a suitable slot 39 in the wall 1', whereby this handle member can be readily grasped by the purchaser for admitting the material 'from the supply pipe 34 into the receptacle 2.

After the receptacle 2 has been filled, the coin expressor is returned upwardly to its normal position, illustrated in Figure 6, thus releasing the lower end of the rod 9 from the perforation in the arm 40, which is secured to the valve stein 4 of the lower valve 33. YThis operation will permit the lower valve 33 to be operated by means of a handle member 42, so as to open communication between the receptacle 2 and the nozzle 43, which is connected with the sleeves 31 and extends outwardly through the wall 1 through the opening 39 thereof, so that the purchaser can readily obtain the contents of the receptacle 2 by operating the handle 42 to open the valve 33. f.

It will be noted in Figures 8 and 9 that I have disclosed the specific type of valve to be used,l 'which is preferablyA a two-way valve as illustrated, so that when the arms 37 and 40 are locked by means of the rod'9,

illustrated in Figures 8 and 9, so that no liquid or other material can pass therethrough. In order to return the valve mem- 'these valve members will be in the positions bers 32 and 33 to theirV locked positions, I f

provide suitable coil springs 44, having one of their ends attached to a perforated lug 45 on the valve stem and the other end attached to a suitable bracket 46, formed on the side of the receptacle 2 in the case of the lower valve member 33, while the coil spring 44 has one of its ends attached to a bracket 47, secured to the inner face of the wall 1.

In Figure 11, I have illustratedia diagrammatic View, including a main supply tank 48, having communication with an indicating receptacle 49, which will indicate to the attendant that only a certain amount of .liquid or other material is contained within the tank 48, so that the supply in the tank 48 can be replenished before the entire amount has been drawn out.

In the operation of my improved device, for dispensing liquid materials, a coin is first deposited within the chute 15', the coin gravitating downwardly to the stop member 14, the finger plate. 22 is then engaged by the fingers or hand of the operator to force downwardly upon the rod 19, which will actuate the coin expressor forcing the same downwardly within the groove 12 to engage the coin and force both the coin and the coin expressor beyond the stop 14, this operation releasing the arm 37 of the valve 32, so that the purchaser can readily grasp the handle member 3S andV open the valve 32 to permit the material from the supply pipe'34 to pass into the container 2. After the container 2 has been filled, the valve 32 is closed and the rod 19 moved upwardly again to its normal position, illustrated in Figure 6, to disengage the rod 9 from the arm 40, to release the valve 33, the upper end of the rod 9 again engaging the arm 37 of the valve 32 to retain this valve in its closed osition until another coin has been insertedO within the chute The valve 33 having been released, the pur- Chaser grasps the handle and rotates the l UO valve member to open communication be tween the receptacle 2 and the delivery spout 43, whereby the contents of the receptacle 2 can be readily drawn therefrom.

From the above description, taken in connection with the accompanying drawings, it will be readily apparent that I have provided a dispensing. device, wherein the contents of the main receptacle cannot be drawn therefrom without irst depositing the required amount ot' coins or tokens in the proper slots provided therefor and only the actual amount or' material can be drawn `from the container' 2 by depositing the requisite amount of coins or tokens in the chute l5.

IVhat I claim is:

1. In a vending device the combination of a receptacle having inlet and outlet ports, valves controlling said ports, valve control members for said valves rotatable in parallel spaced planes, a rod reciprooable intermediate said valve control partsand adapted to engage said parts respectively at opposite ends of its stroke.

2. In a vending device the combination of a receptacle having inlet and outlet ports, valves controlling said ports, a pivoted control member for each of the valves, the pivots for said control members being in substantial align-nient and a. rod reciprocable between said control members and of a length adapted to disengage one of said parts when it engages the other.

3. In a vending device the combination of a receptacle having inlet and outlet ports, valves controlling said ports, pivoted control members for said valves adapted to operate in parallel spaced planes, said control members formed to receive a latch, a reciprocal latch rod operable between the control members and of a length to disengage one when it engages the other of said members.

4t. In a vending device the combination of a receptacle having inlet and outlet ports, valves controlling said ports, a pivoted valve control member for each valve, said control members operable in parallel spaced planes, spring means associated with said members to normally close the valves, a latch rod reciprocable between said control members adapted to disengage one when it engages the other, and spring means operableV on said latch .rod to keep it normally in locking engagement with the inlet valves control member.

In testimony whereof I affix my signature.
